Did I screw up here by not setting this up properly? I just realized I never let MB scan for any artwork aside from the front cover. Tried it once but some of the artwork in those folders are PNG's at 10's of megabytes each and it slowed MB down a lot and since I really didn't need to display all the artwork in MB I just disabled it again.
Still, it moved the Artwork folders that were in the same directory as the flac files, but not if it was in one level above.
Edit:
Just wanted to add the possibility of this being an error with the regex formula used. It moved folders and files with this structure:
AlbumName1/Info/textfiles
AlbumName1/flacfiles
But if that "Info" folder had another folder inside it, like:
AlbumName/Info/SubFolder/textfiles
That folder, along with the files inside, were not moved.
